Anyone remember when the US had a metrification program? Kids were to be taught it in school. Signage was dual dimensioned. Don't remember what happened to it, but we probably had an election. What one side likes the other side by definition hates -- even if it doesn't.

Oddly.. I thought that even N American car makers switched to Metric .. Years.. ago.
And that only building/construction and aviation industries build in Imperial (or at least the 'murican version ) measurements

When I was in high school, (70s) the only thing we ever worked with in science classes was metric, and allegedly the US was all going to be metric "soon". Wikipedia says: "The Metric Conversion Act is an Act of Congress that U.S. President Gerald Ford signed into law on December 23, 1975.[1] It declared the metric system "the preferred system of weights and measures for United States trade and commerce", but permitted the use of United States customary units in all activities."

Honestly metric really is a lot better. I grew up with imperial, but as an engineer have to use all sorts of unit systems at my job and metric is easily the best. Once you get used to it it's quite a bit easier to deal with.
